  • Patent number: 10693544
    Abstract: Multiple antennas of a beamformer may simultaneously transmit wireless signals at different frequencies. The signals may comprise synchronized, identical wireless commands, each at a different carrier frequency. The transmitted signals may constructively and destructively interfere with each other at a receiver antenna, to form a beat signal. When the transmitted signals constructively interfere, the beat signal may cause a voltage in the receiver to exceed a threshold voltage. The threshold voltage may be a minimum voltage at which a device, which is operatively connected to the receiver antenna, is able to perform energy harvesting or wireless communication. The beamformer may operate under blind channel conditions, because the transmitted frequencies may be selected in such a way as to maximize peak power delivered under all possible channel conditions. The beamformer may deliver wireless power to a sensor or actuator that is located deep inside bodily tissue.

    Abstract: Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) having partially coherent antennas may be configured for simultaneous transmissions on groups of antennas (e.g., multiple pairs of antennas). To achieve the benefits of simultaneous transmissions using groups of antenna that are partially coherent, without having the transmissions affect each other (e.g., interference), the UE may apply a hybrid closed-loop multiple-input multiple-output (MIMO) scheme among each antenna in the antenna groups where phase coherence can be maintained. Following the hybrid closed-loop MIMO scheme, the UE may apply a transparent diversity scheme across each antenna of the groups. Alternatively, the UE may first apply the transparent diversity scheme and next apply the hybrid closed-loop MIMO scheme.

  • Patent number: 10531412
    Abstract: Wireless communication is performed by stations (nodes) in a wireless mesh network by forming nodes into a mesh network without the need of network-wide synchronization and without needing to form active links between potential neighbors. Nodes obtain information on neighbors in the network by listening to transmitted beacons from these nearby nodes. Synchronization and active links are established when a data transmission session is triggered and initiated by the route setup process. The link formation process performed when establishing a new route performs both beamforming and synchronization. In situations in which a new route does not intersect other active routes then independent synchronization is performed; but when intersecting routes exist, the new route is synchronized with all intersecting routes where nodes are configured to serve both routes.

    Abstract: Methods are provided for HARQ with channel repetitions. In one novel aspect, the user equipment (UE) receives the resource grant and determines the type of the grant as being the initial resource grant or the secondary resource grant. The initial resource grant carries full control information and the secondary resource grant carries partial control information. In some embodiments, the determination of the type of the grant is based on the RNTI or the payload size. In another embodiment, the UE performs data retransmission based on information from the secondary resource grant and the initial resource grant. In another novel aspect, the UE receives higher layer, such the RRC layer. The UE subsequently receives UL or DL secondary resource grant for both initial transmission and the re-transmission.
